Until the mid-1980s, HUD maintained separate Minimum Property Standards for different types of structures. Since that time, HUD has accepted the model building codes, including over 250 referenced standards and local building codes, in lieu of separate and prescriptive HUD standards. However, there is one major area of difference between the MPS and other model building codes — durability requirements. Homes and projects financed by FHA-insured mortgages are the collateral for these loans, and their lack of durability can increase the FHA’s financial risk in the event of default. More specifically, the model codes do not contain any minimum requirements for the durability of items such as doors, windows, gutters and downspouts, painting and wall coverings, kitchen cabinets and carpeting. The MPS includes minimum standards for these, and other items, to ensure that the value of an FHA-insured home is not reduced by the deterioration of these components.
